5 Cold-Data Infrequent access but significant efford Example: Svalbard Global Seed Vault forgotten vegetables => Log Term Preservation! 5

6 80% of Data Never Accessed After 90 Days 6

7 When Is Long Term Preservation Needed? It depends Delete trash data as soon as possible! Don t store, don t backup, don t archive That is most efficient for trash data Deduplication will not solve this problem! 2. Select worth data It can be hot or cold Put Right Data on Right Storage at Right Time 7

8 Long Time Preserving Data up to 80 Years required Example: Aircraft construction data Which storage medium and architecture will meet this requirement? 8

9 Bit Error Rate of Tape is 10,000 Times Lower Than Disk Seagate Constellation ES.2 StorageTek T10000D How long is data transferred before an uncorrectable error? 9

10 Bit Error Rate of Tape is 10,000 Times Lower Than Disk Seagate Constellation ES.2 StorageTek T10000D 9 days 165 years Equivalent to 40 RAID rebuilds per year per disk! Higher disk capacities = Longer rebuild times = Increasing data loss exposure 10

11 You can have all the tapes in the world, but that won't do you any good without hardware to read them. Jory Prum, LucasArts veteran 11

12 Don t forget the Cables, Interface and Drivers Old Device Cable Interface Driver Computer? Do Not Ignore It Do Validate it! Do Migrate it! Keep up with Technology Changes 12

13 All Data must be Accessable during Life Cycle! 13

14 Long Term Preservation Make sure data is unchanged Make sure data is valid Checksum protection? Re-archive if needed 14

16 Oracle Hierarchical Storage Management Right Data Right Storage Right Time Lower Costs, Improve Efficiencies, Ensure Access 16

17 Archiving with Oracle HSM Lower Costs Backup and Archiving Tiered Storage Private Storage Clouds Object Cloud Storage Oracle Archive Cloud Improve Efficiencies Policy based movement Limitless scalability Horizontal scaling Automated media migration End to end data integrity validation (DIV) Fixity Ensure Access Open formats Product integrations High Availability Remote Archiving OKM support 17

18 Save 77% by Archiving Rarely Used Data Save 20x on Backup Software This savings alone pays for entire archive solution! $1,600,000 $363,000 Archive Software Archive Storage Backup Software Backup Disk Primary Disk Backup Only Backup and Archive 18

19 OpenStack Swift API Applications Standard POSIX File System API Storage Abstraction Layer (Oracle HSM) Manage Tiered Storage with Oracle HSM Primary Storage Archive Storage 19

20 Improve Efficiency with Policy-based Data Movement Types of Policies: Archiving, staging, releasing Number of copies Preferred media type Recycling tape volumes Media migration DIV Fixity Hierarchical Storage Management and Archive Management Policy Characteristics: Name pattern Owner Group Size Access age 20

21 How Oracle HSM Simplifies Management 1 Application writes file to StorageTek QFS file system 2 Archive copies created based on policy 3 Application requests file and the file is retrieved from Oracle HSM Application Disk Cache Archive Devices 21

22 Oracle HSM provides transparency for applications 1 2 Application only knows that it wrote a file And brought it back Application Disk Cache Archive Devices 22

23 Achieve Massive Scale with Oracle HSM Volume Capacity Throughput >1 billion files per file system Users with 7 billion+ files Scale to 1EB+ Multiple users with 40+PBs Achieve 10s of GB/s by scaling horizontally Ingest at 5+ GB/s 23

24 Increase Data Ingest Rates by 10X Tape I/O Horizontal Scalability Ingest >1 PB of data per day Use 10 servers to archive data instead of 1 Perform faster migration of data to new tape drive technology Enable the use of commodity servers 24

25 Enterprise Scalability: Horizontal Tape I/O License Cost Effective Scale Out Architecture Metadata Server (MDS) QFS Clients Metadata controlled by MDS MDS and QFS clients read/write to disk I/O for tape read/write comes from MDS and QFS clients No bottleneck I/O load spread evenly across all servers Primary Disk Tape Storage Tier Yellow = metadata / control path Black = disk data path Red = tape data path

26 Oracle HSM Automated Media Migration Leverage higher density formats with the efficiency of automatic migration Policy-based for automatic, behind-the-scenes migration Migrates multiple data streams without impacting production Seamless file system management 26

27 Oracle HSM Automates Data Integrity Validation Set policy-based DIV audits Verify integrity on each read, write, or any time Dedicate tape drives for DIV audits Self-heals Automatically Supports StorageTek T10000C/ T10000D and LTO 5/6/7 27

28 Oracle HSM Ensures Long Term Access with Fixity Support Validates file remains unchanged Verifies checksum on each read, write, or copy of a file Supports industry standard checksums: MD5, SHA-1, SHA-256, SHA-384, SHA

29 The Need for Open Formats Ensure Access Support movement of data between different systems Provide protection for data recall separate from the archive system Simplify migration from one storage medium to another 29

30 Oracle HSM supports Open Formats Tape Archive (TAR) Primary Use case: Long term storage Collects many files into one archive data set Standard established in 1988 and 2001 Linear Tape File System (LTFS) Primary Use case: File interchange Describes layout of data structures stored on tape Introduced in 2010 ISO standard established in

31 Ensure Future Access with LTFS Format Support Import LTFS formatted tapes Export archive data onto LTFS formatted tapes LTFS Access Import Export FILE INDEX FILE LTFS Format Oracle HSM Archive FILE INDEX FILE LTFS Format 31

32 Oracle HSM Integrates with WebCenter Content to Ensure Access Throughout Data Lifecycle WebCenter Content Ingest Access Collaboration Search Reuse Storage Abstraction Tiered Storage Cost Effective Dynamic Policy Based Storage Virtualization Content Experts Storage Experts 32
